The West End of London (more commonly referred to as simply the West End) is an area of Central London containing many of the city's major tourist attractions, shops, businesses, government buildings and entertainment venues (including the commercial s).

The use of the term 'West End' began in the early 19th century to describe fashionable areas to the west of Charing Cross. For strategic planning, the area is identified as one of two international centres in the London Plan.

While the City of London or the Square Mile is the main business and financial district in London, the West End is the main commercial and entertainment centre of the city. It is the largest central business district in the United Kingdom comparable to Midtown Manhattan in New York City, the Shibuya district in Tokyo or the 8th arrondissement in Paris. It currently ranks as the most expensive location in the world in which to rent office space, beating Tokyo in December 2013.
